DiffLok caps

DiffLok capsTubes on all Markes’ TD autosamplers are sealed with unique DiffLok™ caps, which simply push onto both ends of every tube. DiffLok caps use Markes’ patented diffusion-locking technology (also used in SafeLok tubes), to preserve sample integrity by preventing both analyte loss and artefact ingress.

DiffLok caps ensure that even volatile analytes are successfully retained, guaranteeing reproducible results for standards at the beginning and end of multi-tube sequences.

DiffLok caps maintain sample integrity throughout the analytical sequence

DiffLok caps remain on the tubes throughout an analytical sequence. This preserves sample and tube integrity before and after desorption, but at the same time also simplifies the automatic TD process, thus optimising uptime and productivity. DiffLok caps have been field-proven to seal sampled and blank tubes much more effectively than alternative PTFE push-on caps incorporating PTFE-coated O-rings.

DiffLok caps are available for ¼-inch and 6 mm o.d. tubes, and in stainless steel or inert-coated stainless steel. Inert-coated caps are only ever required for the sampling/desorption end of the tube when sampling reactive compounds. Replacement O-rings are also available for routine maintenance of the caps.
